Is there a way to stay up late every day without overdraft health?
If you are a reader who comes in with expectations, rong’er will tell you with great regret: don’t be silly, no!
Never stay up late without restraint because you are young. The price of staying up late when I was young will have to be paid in the future.
What are the hazards of staying up late for a long time?
Staying up late can be broadly divided into two types: staying up late and staying up late and staying up late and getting up early. Both of them stay up late, but the former guarantees 7-8 hours of sleep, while the latter keeps up late and lacks sleep. Let’s look at the first one first.
1、 The harm of staying up late
Compared with going to bed late and getting up early, going to bed late and getting up late basically guarantees sleep time, but it is still harmful to health. The specific aspects are as follows:
① Decreased sleep quality
22:00 ~ 6:00 and 2:00 ~ 10:00, although the sleep time is also 8 hours, the sleep quality of the latter is far worse than the former. After all, there are still a few people who are active at night, and at six or seven o’clock in the morning, everyone is basically active. There are all kinds of voices, cars, birds, and the sun is shining brightly. Or outsiders call in at random. In short, the external environment has thousands of ways to destroy your sleep quality.
② Easily depressed
Poor sleep quality will directly affect the mood. A study published in neuroimage in 2014 found that compared with those who slept early, those who slept late had decreased integrity of white matter, including frontal lobe, temporal lobe, cingulate gyrus and corpus callosum. Although it is not sure what impact this decline in integrity will bring, it is predicted that there will be some changes in cognitive function, and it is easy to be troubled by depression.
③ More prone to bad habits
Going to bed late will certainly prolong your activity time, so you will inevitably catch some bad habits. For example, eating supper, or smoking and drinking too much. Whether it’s for work or pure entertainment, it’s hard to avoid starvation after staying up late at night. At this time, people need to replenish their energy. However, those who regularly eat midnight snack will have a long-term burden on their stomach and are more likely to develop gastric cancer than ordinary people. As for the harm of tobacco and alcohol, it is also well known. Rong’er will not say much here.
④ It will affect your breakfast
According to rong’er’s intuitive feeling, starting at 7:00 on the weekend will make people feel that the time of the day is getting longer. I can get up and have breakfast, watch a variety show, and then go out to play. But if you start from 10 o’clock, breakfast is basically skipped, and it is obviously unwise to starve your stomach. Moreover, there is only afternoon left on a beautiful day, and the balance of a proper holiday is insufficient. How can we happily welcome the “beautiful” Monday?
2、 The harm of going to bed late and getting up early
Staying up late for a long time and not getting enough sleep will do great harm to your health.
① Obesity
The fattest is “staying up late + eating snacks”. A study by Columbia University found that people with insufficient sleep should consume an average of 300 more calories per day than those with sufficient sleep. Among them, women who sleep late are more likely to gain weight than men. Because women are hungry during staying up late, they are more inclined to eat various snacks, pizza, potato chips, candy and ice cream. These excessive calories are difficult to consume, which is easy to cause obesity.
② Cause type 2 diabetes
Researchers at the University of buffalo tracked 1455 volunteers for six years and counted their average weekly sleep time during work. The results showed that those who slept less than 6 hours a night on average had a 4.56 times higher probability of impaired fasting glucose than those who slept more than 6 hours a day. Researchers said that impaired fasting blood glucose is the intermediate stage between “normal” and “diabetes”. If we do not pay attention to it, it is easy to develop type II diabetes.
③ Reduced libido
Like women, men have a periodic hormone curve. Hormone secretion at night should be low, but continuous work stimulates the cerebral cortex and forces glands to secrete too much hormone. In the long run, it destroys the circadian rhythm of the human body’s biological clock and makes men’s sex hormone secretion disordered, so the proportion of sexual dysfunction of those who stay up late is higher. Sleep is an element of maintaining sexual power. Both men and women should resist staying up late for illegitimate reasons.
④ Cause endocrine disorder
Rong’er, who is still affected by staying up late, just wants to say: staying up late is a pleasure for a while, and her skin will be ruined for the whole year! The pimples on your face should not be too tough. In fact, it’s not only the skin that deteriorates. Women who stay up late are twice as likely to have irregular menstruation as those who have regular schedules. They are also more likely to have dysmenorrhea and mood swings. In addition, according to experts from Harvard Medical School and Boston Brigham and women’s Hospital, the proportion of cancer among women who often work night shift is 1.5 times that of women who work day shift. And the more times I work night shift, the greater the risk. Therefore, it is suggested that the students on night shift should not be too frequent.
⑤ Affect emotional system
Reduced sleep will reduce attention and alertness, and on this basis, reduce overall cognitive function, such as affecting the emotional system. People who lack sleep for a long time tend to have fluctuating emotions, and when something goes wrong, they will become angry because of their irritability. Lack of spirit and concentration will also lead to the decline of learning and working ability. This kind of unfavorable things will also cause depression and anxiety.
⑥ Resulting in increased mortality of various diseases
Staying up late is not necessarily fatal, but for people with certain diseases, staying up late will cause sudden death. Especially for patients with basic cardiovascular diseases, such as hypertension and hyperlipidemia, long-term lack of sleep can lead to arrhythmia, angina pectoris, and even insufficient blood supply to cardiovascular and cerebrovascular vessels or cerebral hemorrhage, which is very easy to cause sudden death.
3、 Indirect harm of staying up late
People who stay up late for a long time not only have their physical health affected, but also sometimes affect their performance in life and work, and the consequences may be more serious.
For example, fatigue driving – statistics from the American Academy of sleep medicine show that about 1 / 5 of car accidents are related to fatigue driving, more than 80000 people doze off while driving every day, and 250000 car accidents are related to lack of sleep every year. As mentioned above, reduced sleep reduces attention and alertness. However, compared with those who did not sleep all night, those who slept less for a long time were more likely to have accidents.
Another example is the mistakes in some professional fields – the Department of psychiatry of the Faculty of medicine of the Chinese University of Hong Kong once conducted a study on “the impact of overtime work and overnight call on doctors in public hospitals”. Among them, 36.2% of doctors who worked more than 65 hours a week said that they had made medical mistakes. Among doctors who worked less than 50 hours, the proportion was 21.8%. Therefore, lack of sleep time will increase the risk of mistakes.
At the end of the article, let’s make a summary: rong’er thinks that staying up late for a long time can cause both chronic harm to the body and instant tragedy caused by careless mistakes. There are really many harms. Let’s listen to President Xi and don’t stay up late!
